1. A method of making a tungsten trioxide (WO3) electrochromic material, the method comprising:
dissolving a tungsten trioxide source compound in a solvent comprising an alcohol to form a liquid feed stream,
atomizing the liquid feed stream within an oxygen-containing gas to form an aerosol, and combusting the aerosol, thereby forming the WO3 electrochromic material, wherein the WO3 electrochromic material comprises ε-WO3 nanoparticles.
